Fuel cell manufacturing device and manufacturing method

Abstract

A fuel cell manufacturing device includes: a conveying unit for conveying a laminate in which components of the fuel cell are laminated and arranged via an adhesive layer containing a thermoplastic resin material; a heating unit for heating the laminate when the laminate conveyed by the conveying unit is positioned in a predetermined heating zone; a cooling unit for cooling the laminate when the laminate conveyed by the conveying unit is positioned in the predetermined cooling zone after passing through the heating zone; and a pressurizing unit for continuously pressurizing the laminate until the laminate is heated in the heating zone and cooled in the cooling zone.

What is claimed is: 
     
         1 . A fuel cell manufacturing device comprising:
 a conveying unit that conveys a stacked body in which constituent elements of a fuel cell are stacked via an adhesive layer containing a thermoplastic resin material;   a heating unit that heats the stacked body when the stacked body conveyed by the conveying unit is positioned in a predetermined heating zone;   a cooling unit that cools the stacked body when the stacked body conveyed by the conveying unit is positioned in a predetermined cooling zone after passing through the heating zone; and   a pressurizing unit that keeps pressurizing the stacked body since the stacked body is heated in the heating zone until the stacked body is cooled in the cooling zone.   
     
     
         2 . The manufacturing device according to  claim 1 , wherein:
 the manufacturing device includes a double belt press device; and   the double belt press device includes
 a pair of upper and lower belts that constitutes the conveying unit, 
 a heating press portion that constitutes the heating unit and a part of the pressurizing unit, and 
 a cooling press portion that constitutes the cooling unit and another part of the pressurizing unit. 
   
     
     
         3 . The manufacturing device according to  claim 1 , wherein:
 the manufacturing device includes a continuous roller press device;   the continuous roller press device includes a pair of upper and lower roller conveyors that constitutes the conveying unit; and   the upper and lower roller conveyors include a heating press portion that constitutes the heating unit and a part of the pressurizing unit, and a cooling press portion that constitutes the cooling unit and another part of the pressurizing unit.   
     
     
         4 . The manufacturing device according to  claim 1 , wherein:
 the pressurizing unit includes a jig capable of pressurizing the adhesive layer while sandwiching the stacked body in a stacking direction of the stacked body; and   the jig includes a pair of plates that sandwiches the stacked body, and a positioning member that suppresses positional deviation of the plates in a direction orthogonal to the stacking direction of the stacked body.   
     
     
         5 . A fuel cell manufacturing method comprising:
 heating and pressurizing a stacked body including an adhesive layer containing a thermoplastic resin material; and   cooling and pressurizing the stacked body after the heating and pressurizing, wherein the stacked body after the heating and pressurizing is supplied to the cooling and pressurizing in a state in which at least a predetermined load on the adhesive layer is maintained.
